Features and specifications

Use this information to view specific information about the compute node, such as compute node hardware features and the dimensions of the compute node.

  1. Power, cooling, and chassis systems management are provided by the IBM NeXtScale n1200 Enclosure chassis.
  2. The operating system in the compute node must provide USB support for the compute node to recognize and use USB media drives and devices. The IBM NeXtScale n1200 Enclosure chassis uses USB for internal communication with these devices.

The following table is a summary of the features and specifications of the NeXtScale nx360 M4 compute node.

Microprocessor (depending on the model):
  • Supports up to two multi-core microprocessors (one installed)
  • Level-3 cache
  • Two QuickPath Interconnect (QPI) links speed up to 8.0 GT per second
  • Use the Setup utility to determine the type and speed of the microprocessors in the server.
  • For a list of supported microprocessors, see the IBM ServerProven website.
  • 8 dual inline memory module (DIMM) connectors
  • Type: Low-profile (LP) double-data rate (DDR3) DRAM

The NeXtScale nx360 M4 compute node complies with ASHRAE class A3 specifications.

Server on2
  • Temperature: 5°C to 40°C (41°F to 104°F)3
  • Humidity, non-condensing: -12°C dew point (10.4°F) and 8% to 85% relative humidity4,5
  • Maximum dew point: 24°C (75°F)
  • Maximum altitude: 3048 m (10,000 ft)
  • Maximum rate of temperature change: 5°C/hr (41°F/hr)6
Server off7:
  • Temperature: 5°C to 45°C (41°F to 113°F)
  • Relative humidity: 8% to 85%
  • Maximum dew point: 27°C (80.6°F)
Storage (non-operating):
  • Temperature: 1°C to 60°C (33.8°F to 140.0°F)
  • Maximum altitude: 3,050 m (10,000 ft)
  • Relative humidity: 5% to 80%
  • Maximum dew point: 29°C (84.2°F)

  • Temperature: -40°C to 60°C (-40°F to 140.0°F)
  • Maximum altitude: 10,700 m (35,105 ft)
  • Relative humidity: 5% to 100%
  • Maximum dew point: 29°C (84.2°F)9
Particulate contamination
  • Design to ASHRAE Class A3, temperature: 36°C - 40°C (96.8°F - 104°F), with relaxed support:
    • Support cloud such as workload with no performance degradation acceptable (turbo-off)
    • Under no circumstance, can any combination of the worst case workload and configuration result in system shutdown or design exposure at 40°C
    • The worst case workload (such as linpack and turbo-on) may have performance degradation
  • Airborne particulates and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the compute node. For information about the limits for particulates and gases, see Particulate contamination.
  1. Onboard LSI software SATA RAID supports SATA drives and Solid state drives (SSD). SAS drives are not supported for software RAID. The booting and use of internal drives with VMware is not supported with the ServeRAID C100 (software RAID) controller.
  2. Chassis is powered on.
  3. A3 - Derate maximum allowable temperature 1°C/175 m above 950 m.
  4. The minimum humidity level for class A3 is the higher (more moisture) of the -12°C dew point and the 8% relative humidity. These intersect at approximately 25°C. Below this intersection (~25°C), the dew point (-12°C) represents the minimum moisture level; above the intersection, relative humidity (8%) is the minimum.
  5. Moisture levels lower than 0.5°C DP, but not lower -10 °C DP or 8% relative humidity, can be accepted if appropriate control measures are implemented to limit the generation of static electricity on personnel and equipment in the data center. All personnel and mobile furnishings and equipment must be connected to ground via an appropriate static control system. The following items are considered the minimum requirements:
    1. Conductive materials (conductive flooring, conductive footwear on all personnel who go into the datacenter; all mobile furnishings and equipment will be made of conductive or static dissipative materials).
    2. During maintenance on any hardware, a properly functioning wrist strap must be used by any personnel who contacts IT equipment.
  6. 5°C/hr for data centers employing tape drives and 20°C/hr for data centers employing disk drives.
  7. Chassis is removed from original shipping container and is installed but not in use, for example, during repair, maintenance, or upgrade.
  8. The equipment acclimation period is 1 hour per 20°C of temperature change from the shipping environment to the operating environment.
  9. Condensation, but not rain, is acceptable.
